SL 43 Double beam Chicken Glasses

Product Overview

The SL 43 double-beam poultry frame is noted on the product drawing at about 4.5 cm wide, 2.8 cm high and 1.6 g a pair. The double-beam name describes the twin bar that crosses the beak: instead of a single strip, two beams seat one behind the other, spreading the grip across two contact points. A thin locking pin is shown beside the frame, threading through the nostrils to hold the beams in place. This construction is aimed at commercial layer houses and breeder pens on slats, where the birds stay active all day and the frame must not twist or slip.

With the twin beams seated, the outer wings cover each eye from the straight-ahead direction. A hen still recognizes the feed trough and the water line, but its focus on the tail and back feathers of the bird immediately in front is broken, which cuts the chain of repeated pecking. The red plastic is used because it softens strong sun inside closed barns, where long artificial lighting can stir restless behavior. This pack contains the SL 43 twin-beam frames in the large and medium size range.

Key Features and Benefits

• Twin-beam two-point grip - Two beams bridge the beak at once, so the frame holds steadily instead of twisting to one side.
• Printed 4.5 cm span - The marked width and 2.8 cm height confirm the fit on large and medium breeds before a buyer commits to a batch.
• Light 1.6 g pair - The thin wings add almost no weight, so active hens keep moving and feeding normally.
• Survives slatted-floor scratching - The pin lock stands up to heavy scratching, which suits houses built on slats rather than litter.
• Pin-locked security - The thin pin through the nostrils prevents the beams from slipping during a full laying cycle.
• Thin plastic wings - Softened edges avoid pressure marks where the wings rest against the face.

Materials and Quality

The twin beams are formed slightly thicker than a single strip, which gives the frame a firm seat without adding weight. The pin bore through the beams is shaped by the die, so the pin lines up cleanly during fitting. We bend-check production frames open and closed before packing, and we check that the pin threads in without forcing. Any pair with a sharp edge along the wing is rejected, because a rough corner can mark a hen's skin over weeks of wear.

How to Use and Maintain

In a lit handling pen, hold the hen securely, seat the twin beams across the beak, and thread the locking pin through the nostrils to hold them. Check that the bird can still open its beak to reach the trough. After a day, walk the house and confirm the frames sit centered rather than twisted. Between batches, wash the frames in disinfectant solution, wash off the residue, and inspect each beam for hairline cracks before they go back on the shelf. Fitting takes only a few seconds per bird, so a crew can equip a whole slatted barn during one routine handling visit. If a frame looks twisted after a day, recenter the twin beams rather than forcing the pin tighter.

Applications

The SL 43 is built for commercial layer houses on slatted floors, where hens scratch constantly and a single-beam frame would shift. Breeder pens also use the twin-beam lock, because active males need a frame that survives mounting and chasing. Closed barns with long artificial lighting benefit from the red wings, which soften the sun that often triggers restless pecking. On slatted floors, where the hens scratch at the gaps all day, the pin lock keeps the frame centered through a full laying cycle. Barn crews fit the frames during the regular catch, so the extra work adds only seconds per bird and does not disturb the feeding routine.

Importers recommend the twin-beam model to farms that have lost frames with simpler shields, because the two-point grip solves the slipping problem. The 1.6 g pair packs densely, which keeps freight cost low, and the pin is a standard spare part sold separately. Commercial operations switching from single-beam shields order this frame as the default anti-pecking option for cage and slat systems.

Frequently Asked Questions

Q1: Why two beams instead of one?

The twin beams grip the beak at two points, which keeps the frame centered on active birds and on slatted floors where scratching is heavy.

Q2: Is the locking pin included?

Yes, the listing shows the twin-beam frame together with the thin pin. Spare pins are available if any are lost during fitting.

Q3: Will the frame block eating?

The wings sit in front of the eyes and leave the beak free to open. Check the house after a day, and recenter any twisted frame.

Q4: Which houses suit this model?

The twin-beam lock is aimed at commercial layer houses, breeder pens and slatted-floor systems. For small free-range flocks, the pegless model may be simpler.
